' 4 Claims.

This invention relates. to' a float controlled valve and more especially to an "automatically controlled fluid transfer or diverting apparatus and is a continuation in part of'my pending ap plication for Automatic Float Transfer Valve hearingserial No. 655,293" filed March 18, 1946, and now abandoned.

The primary object of the present" invention is the provision of an apparatus of this character, wherein through the workingthereof'fluid is automatically diverted from one receptacle to another, and this is efiected by' a float controlled valve, the apparatus being of novel construction andgis. unique in" the: assembly" of its parts, which are. actuated through automatic control action".

Another. object of' the present invention is; the provision of. an. apparatus of this. character, wherein its use with. oiI tank'systemsi'wi'll enable the oil flow to be-d'ivertedfrom:onetank-to an. other; and thereby regulating the lever ofth'eoil in. therespective. tanks for the; filling thereof;

A furtherobject of the present invention is the provision of an apparatusof" this: character, whichis simple in construction, thoroughly reliable and efficientin operation; and automatic in'the working thereof, positive in action; strong, durable and inexpensive tomanufacture and install.

With these and other objects in viewthe" in:

vention consists: in the-featuresof. construction, combination and arrangement of partsas will-be hereinafter more fully described, illustrated in the accompanying drawing; which discloses the preferred embodiment of the invention and pointed out in the claims hereunto appendeda In theaccompanyingdrawing:

Mounted for-vertica1sliding movement. intheguide portions I5 and Hi respectively is'thefloat' carrier 11 on which is. mounted for-sliding'mcvement the float I81 If." the"l'evel'.of.the contents of the tank I0 is, bel'owthe portion L6 the. float I8 will rest thereon... However, as; the, level. .off'the contents rises. the; float. [8' will ride". the level, of the contents of the tanl'c. HT and; willslid'e upwardly onthe carrier. [1 asthelevelof 1711610011- tents. rises,

The carrier ll. isjprovidedl'with.a'pluralityof relatively spaced. traverse. openings lfllwhihhreceive a stop pin 201' Thus. with thepin til -selentivel'y engaged in either. of. the. openingsr 1.9. the float. l8;'will1.upon engagement. with the pin 2]) cause the float [8' to slid'ethecarrier tTupwardIy withinthe guide portions ['5' and I 62 respectively.

The upper. end oithe; carrier [1. whichiprojects abovathe upper-periphery of. the tank lll..is;pr.o-.- videdl with a projection .2 l which. is. engaged .in

the. elongated eye. or. loo-p portion 22.. of the L=shapedoperatinglever 23;.

The. lever 2 3. is: provicfld. with. a horizontal. poretion which is paralleltd a plane passingtrans'r versely of the. tank. Ill. and averticalportion 25 which is parallel to the vertical axis oil the tank, (0..

The lower end of'the" portion 25oithe lever 2.3 is: provided" with a yoke 26' having, portions. 2] and "28 respectively. 'I'he'lower end" ofthe portron-21* has a. rightangularly. directed" extension 29 having an enlarged aperturedearxiifl" on; the outer" end thereof, while" the lower; end. of. the portion 2 8- is: provided with a rightangularly directedextension 31 havingan' enlarged ap'entured" ear 32- on the" outer endjrthereoff Inter:- medi'ate of the portions 27 and 28' there: isconinected thereto a V-shaped right'angularly and inwardly directed proj ection'33" the operatioirof The housing 3'! has a closed bottom 46 and an open-top 4! and the outer surface of the housing 3'! adjacent the open top is provided with screw threads 42. The screw threads 42 detachably engage the internally threaded annular flange 43 of the cap or cover 44.

Mounted for reciprocation in the housing 3'? is the valve body or piston 45 having the separate transverse flow passages 45 and 4"! respec tively therein. The passages 45 and 47 will alternately communicate with independent flow or feed pipes 43 and 4%! respectively as will be later described. The pipe 49 will be connected with the flanged inlet 59 of the tank It while the pipe 48 will be similarly connected to another storage tank not shown. The pipes 48 and 48 at their ends opposite to the ends connected to the tanks are connected to the flanged outlets 5i and 52 respectively of the housing 3?. The pipes 53 and 54 are connected to a coupling 55 to a main supply or feeder pipe 55 at one end while the other ends are connected to the flanged inlets 57 and 58 of the housing 3? which are in alinement with and diametrically opposed to outlets El and 52 respectively.

The lower end of the valve body or piston 4-5 is provided with a centrally located smooth bore 59 in which is seated the upper end of the expansion spring 63 the lower end of which rests on and engages the inner surface of the bottom 40 of the housing 31.

The upper end of the valve body or piston 45 engages the enlarged lower end iii of the operating pin 62 which is slidably mounted in the centrally located flanged opening 63 in the cap 44. The upper end of the pin 62 has a head or button 64 thereon which will engage the V- shapedprojection 33 on the portions 28 and 29 as will be later described.

Viewing Figure 4 it will be noted that the valve body or piston 45 is provided with a groove 65 which extends longitudinally thereof and engages an inwardly directed pin 65 on the inner surface of the housing 37. 'The engagement of the pin with he groove prevents rotation of the valve body. or piston 45 within the housing 31.

In operation with the float l3 resting on the portion [6 the pin 52 is manually depressed engaging the valve body or piston 45 and urging the same downwardly in the housing 3'! against the action of the spring en. The projection 33 is then engaged with the head 64 of the pin as in Figure 5. In this position the passage 47 of the valve body or piston 45 is in alinement with pipe 54 and inlet 53 and outlet 52 and pipe '49. Thus the flow from the main line 56 will enter pipe 54 passing through passage 41 out through outlet 52 into pipe 49 and thence into .inlet 58 of the tank H3. As the level of the contents in the tank It! rises it will engage the float l8 causing it to slide upwardly on the carrier I1 until it engages the pin 20. The float will then urge the carrier ll upwardly causing the lever 23 to be moved to the position'shown in dotted lines Fig. l. The action or the lever causes the projection 33 to become disengaged from the head 64 of the pin 62. The spring 60 will then urge the valve body or piston 45 upwardly to the position shown in Figure 6.

In this position the passage 45 of the valve body or piston 45 is in alinement with the inlet 51 and pipe 53 and outlet 5| and pipe 48. Thus the flow from the main pipe 56 will be diverted to another storage tank through the pipe 48, the flow through passage 46 and outwardly of outlet 5|. 1

If the tank I'll later becomes empty the valve body or piston is manually reset as previously described and the operation will be repeated as previously described. It Will be noted that the pin 28 is selectively engaged in the openings 19 to cause the float to engage the pin at any desired level of the contents of the tank.

It will be seen, therefore, that through an oil distributing system wherein the invention may be used, that a series of tanks may be selectively filled as soon as one of the tanks is filled and so on until all tanks are filled.

Having thus described the invention what is claimed as new and desired to be covered by Letters Patent is:
